    Waste Heat Boiler - an overview | ScienceDirect Topics

    Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.

    Applying ASME Boiler Code to Steam Generation Systems

    Jan 01, 2013 · (Page 1) The main focus of the ASME boiler code is on power boilers, rather than on petroleum refinery or petrochemical heaters, so definitions are sometimes not clear. Furthermore, it can be difficult to define which authority has jurisdiction over steam generation systems in the CPI. Even in the U.S. This article provides guidance on the requirements for stamping within the ASME code and
